"Includes 40 SDS Drum EPROMs, for SDS-1, SDS-7, SDS-9

Up for auction is a black vintage Simmons SDS-1 EPROM-based electronic drum pad in perfect operating condition, including 40 different EPROMs compatible with Simmons SDS-1, SDS-7, and SDS-9 drum synths.

The Simmons SDS-1 is a single voice drum synth that uses 8k or 16k EPROMs. The drum synth can be triggered by hitting the drum pad or via an external trigger input. There is a modulation section on the drum synth that allows you to set the pitch and pitch bend direction, then a separate runtime generator allows you to dial in a random pitch generator that can range from subtle to extreme. Please check out my link below to some MP3s I made with the SDS1 drum synth.

The Simmons SDS EPROM drum pad is confirmed 100% working, ZIF, LED, external trigger, output, and knobs are all functioning properly. All 40 drum sound EPROMs included with this auction have been verified and are also confirmed working."
